# What is the area of 10 radius circle?

## What is the area of 10 radius circle?

=78.5 square inches.

### What is the area of the radius is 10 feet?

The diameter is always twice the radius, so either form of the equation works. This formula reads, “Area equals pi are squared.” Find the radius, circumference, and area of a circle if its diameter is equal to 10 feet in length. so the area is about 78.5 square feet.

What is the radius when diameter is 10?

What is the radii of 10cm?

The radius of the circle: r=10 cm. So. A=π⋅(10 cm)2≈314.16 cm2.

## What is 10cm in diameter?

Ten centimeters is about the diameter of a wiffle ball.

### What is the circumference with a radius of 10?

The circumference of the circle is 20π cm or about 62.8 cm.

What is the radius if my circumference is 10?

Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter, 3.18 centimeters. Divide the diameter by 2. And there you go, the radius of a circle with a circumference of 10 centimeters is 1.59 centimeters.

What is the circumference of the diameter is 10?

31.42cm
Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).

## How do you find the diameter of 10 cm?

If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm. If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter.

### How do you make a 10 cm circle?

Step-by-step explanation:

1. Mark a point X on the centre of your page.
2. To draw a circle of diameter 10 cm, we need to first calculate the radius.
3. Radius = diametre/2 = 10/2 = 5 cm.
4. Now, take a compass and open it to 5 cm.
5. Place the needle of the compass on the point marked X and draw a full circle on the page.

What is the radius of a 10cm circle?

You see the radius is 1/2 the diameter and 1/6 the size of circumference….Look at the table.

10cm 20cm 62.4cm
20cm 40cm 124.8cm

How big is a 10 cm hole?

## What is the formula to find the area of a circle?

Area of a Circle Formula The area of a circle is pi times the square of its radius. The radius is half the diameter. Area = π * (Diameter / 2)2

### What is the radius of a circle with R = 10 cm2?

The radius of the circle: r = 10 cm. So. A = π⋅ (10 cm)2 ≈ 314.16 cm2.

What is the diameter of a 2 foot 2 cm circle?
